Support for user-defined data representations has not been added to MPICH yet. There has not been much demand for it. Rajeev

Hi,
Here is my little test program.
Almost the same as chapter 9.1 of the book " Using MPI-2: Advanced Features of the Message-Passing Interface" from William Gropp, Ewing Lusk, and Rajeev Thakur.
Thanks,
Eric

Hi,
I am trying to use the MPI_Register_datarep functionnality with mpich-3.2, but while executing, I have this error:
ERROR Returned by MPI: 67148823 ERROR_string Returned by MPI: An error occurred in a user-defined data conversion function, error stack: MPI_REGISTER_DATAREP(108): Read and Write datarep conversions are currently not supported by MPI-IO application called MPI_Abort(MPI_COMM_WORLD, 1) - process 0
I have configured mpich-3.2 with: ./configure --prefix=/opt/mpich-3.2_ch3sock --with-device=ch3:sock
Is there anything I have to do to be able to use this functionality?
Thanks,
Eric
